Nhasi pakuvhurwa kweComputex 2019, AMD yakatarisa yakamirirwa kwenguva refu mhuri yeNavi yemakadhi emavhidhiyo emitambo. Iwo akatevedzana ezvigadzirwa zvitsva akagamuchira zita rekushambadzira Radeon RX 5000.
Zvakakodzera kuyeuka kuti mubvunzo yaive imwe yeanonyanya kunetsa pakuunza Navi yemitambo sarudzo. Kunyangwe pakutanga zvaifungidzirwa kuti AMD yaizoshandisa manhamba indices kubva ku5000-series, kambani yakazosarudza zita rekuti Radeon RX 50. Pfungwa iri shure kwezita ndeyekuti inotamba padingindira remakore makumi mashanu iro AMD iri kupemberera gore rino. .
Mukuwedzera, rumwe ruzivo runofadza rwakaziviswa. Iyo Radeon RX 5000 makadhi evhidhiyo akavakirwa pane nyowani GPU yekuvaka inonzi Radeon DNA (RDNA), inova imwe budiriro yeGraphics Core Inotevera (GCN) yakaonekwa makore manomwe apfuura.
Iyo RDNA dhizaini inoita seinopa dhizaini nyowani yeiyo yakakosha unit yeGPU, iyo compute unit, zvichikonzera kuvandudzwa kwesimba rekushanda uye kuita pawachi. Uye zvakare, AMD yaita hutsva hwakawanda-level cache hierarchy muRDNA, iyo inofanirwa kuderedza latency, kuwedzera throughput, uye zvakare kunatsiridza mashandisiro emagetsi. Iyo yakagadziridzwa RDNA graphics pombi inobvumirawo makadhi matsva emifananidzo kuti ashande nekumhanya kwewachi kupfuura kare, zvichikonzera mazinga epamusoro ekuita. Pamusoro pezvo, zvichienzaniswa nemachipi ane GCN architecture, Navi ine yakawedzera compact semiconductor chip saizi, asi kusvika parizvino mugadziri haasati aburitsa ruzivo nezvakawanda.
Pakazere, iyo RDNA dhizaini inopa hukuru hwekuita uye yakaderera latency ine zvirinani mutengo-kushanda. Kuenzaniswa neVega kadhi dhizaini, AMD yakavimbisa kuwedzera makumi maviri neshanu muzana mukuita chaiko pawachi uye 25 muzana yekuwedzera mune chaiyo kuita pawatt.
Sezvakaziviswa pamharidzo, yekutanga poindi yekushandiswa kweiyo RDNA architecture ichave iyo Radeon RX 5000 yakatevedzana yemakadhi emifananidzo, umo makadhi ekutanga evhidhiyo anonzi Radeon RX 5700 achaburitswa. Iwo ese akateedzana achave akavakirwa paNavi chips. , yakagadzirwa uchishandisa 7-nm process tekinoroji paTSMC zvivakwa.
Chinhu chinoshamisa kwazvo cheRadeon RX 5000 nhevedzano ichave tsigiro yavo yePCI Express 4.0 bhazi. AMD irikushingairira kusimudzira pfungwa yekuenda kune imwe vhezheni yeiyo interface ine yakawedzera bandwidth, uye iyo Radeon RX 5000 ichakwana zvakakwana mukambani ecosystem pamwe nerechitatu-chizvarwa Ryzen processors uye mamaboards akavakirwa paX570 chipset.
Mukutaura kwake, AMD CEO Lisa Su airatidza muchidimbu mashandiro evhidhiyo kadhi rekutamba rakavakirwa paNavi chip. Iyo Radeon RX 5700 kadhi yemifananidzo yakafananidzwa neNVIDIA GeForce RTX 2070 muStrange Brigade bhenji. Panguva imwecheteyo, chigadzirwa chitsva che AMD chakazove chinenge 10% nekukurumidza.
AMD inotarisira kutanga kutengesa makadhi evhidhiyo eRadeon RX 5700 muna Chikunguru, asi zuva chairo harisati raziviswa. Nekudaro, AMD yakavimbisa kuburitsa rumwe ruzivo nezve Navi's specs, mitengo, uye kuita payo Inotevera Horizon Gaming chiitiko paE3 musi waChikumi 10, 2019.
